Home range and core area characteristics of urban and rural coyotes and red foxes in southern Wisconsin

open access: yesWildlife Biology, EarlyView.
Second‐order habitat selection is influenced by a variety of factors, including individual‐ and species‐specific traits and resource requirements, as well as landscape characteristics. By comparing home range characteristics across individuals, species, and landscapes, we can draw conclusions regarding whether and how different factors influence home ...

Field Performance of a Genetically Modified Cowpea (Vigna unguiculata) Expressing the Cry1Ab Insecticidal Protein Against the Legume Pod Borer Maruca vitrata

open access: yesAgronomy
Cowpea (Vigna unguiculata) is a vital crop in sub-Saharan Africa, but the legume pod borer (LPB), Maruca vitrata, can cause over 80% yield losses.

‘Using anuran community diversity and Pseudacris crucifer to predict landscape quality across a land use gradient'

open access: yesWildlife Biology, EarlyView.
As human‐modified landscape and climate changes proliferate, maintaining biodiversity and understanding the function and quality of available habitat is imperative. As anurans (frogs/toads) such as Pseudacris crucifer, can be an indicator species of habitat quality and ecosystem productivity, studying the anuran community in a mixed‐land use region ...

Importance of woody patches and vegetation heterogeneity in Texas tortoise microhabitat use

open access: yesWildlife Biology, EarlyView.
Microhabitat sites provide important resources and thermal conditions to reptile species that can vary spatially and temporally. This study assessed Texas tortoise Gopherus berlandieri microhabitat use and its relationship with carapace temperature during their active (April–October) and inactive seasons (November–March) between January 2023 and ...

Changes in Beliefs and Perceptions about the Natural Environment in the Forest-Savanna Transitional Zone of Ghana: The Influence of Religion [PDF]

open access: yes
The potential of traditional natural resources management for biodiversity conservation and the improvement of sustainable rural livelihoods is no longer in doubt. In sub-Saharan Africa, extensive habitat destruction, degradation, and severe depletion of

Growth and age determination of African savanna elephants

open access: yes, 2006
Understanding the population dynamics of savanna elephants depends on estimating population parameters such as the age at first reproduction, calving interval and age-specific survival rates.

Estimating large carnivore populations in an arid fenced reserve using spatial capture–recapture modelling

open access: yesWildlife Biology, EarlyView.
In fenced protected areas where large carnivore populations persist or have been restored through reintroduction, population monitoring is essential to inform management. Robust density estimates are particularly important given the strong influence of large carnivores on ecosystem processes, yet such data remain scarce for arid systems where ...

Community Health Services, Market Access, and Food Insecurity: Evidence From Ghana

open access: yesFood and Energy Security
The role of community interventions such as market infrastructure and health campaigns on household welfare are increasingly gaining attention of policymakers as they seek to identify pathways to achieve the sustainable development goals (SDGs) one, two,

Livestock grazing and geodiversity modulate wild herbivore distributions in an African community conservation area

open access: yesWildlife Biology, EarlyView.
The rapid decline of African wildlife populations demands immediate action to mitigate further losses and restore ecosystems. A key factor influencing wildlife distribution is the relationship between the energetic needs of species and the availability of forage, both in terms of quality and quantity.
